The Brain Needs Animal Fat

Public health officials say these magical plant fats are rich in important PUFAs (polyunsaturated fatty acids) that the human body cannot manufacture and therefore must be obtained from the diet:

What often goes unsaid is that both ALA and LA are found in a wide variety of both plant and animal foods, so it is rather easy to obtain both of these PUFAs, regardless of your dietary preferences, so long as you are including enough fat in your diet. About 2/3 of the human brain is fat, and a full 20% of that fat is a very special essential omega-3 fatty acid called docosahexanoic acid, or DHA. Most vegetable oils are extremely, unnaturally high in LA (linoleic acid), an omega-6 fatty acid that reduces the production and effectiveness of DHA within your body.
